BlueSmirf and LCD Pinouts

Hi! I am working on a small project following this tutorial.
(http://popsci.typepad.com/how20blog/200 ... he-in.html)

I just received all of the parts this morning and have begun assembly. One issue I am running into is the pin outs on the Bluesmirf bluetooth modem. You see on my LCD I have 3 terminals +5v, ground and RX I want to know which pin on the Bluesmirf I should connect the RX terminal to. I have these pin on the Bluesmirf CTS-I, VCC, GND, TX-0, RX-I, RTS-0

I obviously know what GND is but could you help me identify the rest.

Thanks, Joe

CTS: Clear to Send
VCC: +5v
GND: Ground
TX: Transmit data
RX: Recieve data
RTS: Request to send

You don't need or care about CTS, RTS, and RX for your application. RTS and CTS are for handshaking. You would connect the TX on the bluesmirf module to the RX on the LCD.

The I and O at the end of each pin refer to Input or Output from the bluesmirf module. For example, you have TX-O which is transmit from the module so you are ouputting data.

Thanks a ton man. I am kinda clueless when it comes to electronics even though I have been on a International winning robotics team. I was just a measly mechanical engineer. Lets just say I melted too many wires and lost my electronics priveleges.
